JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EA3304 Subject Category: Aeronautical Technology PDF Responsible Representative: Yoshikazu Makino, Aeronautical Technology Directorate, Aviation Systems Research Unit Contact Information: Yasutada Tanabe(tan@chofu.jaxa.jp) Members: Yasutada Tanabe, Hideaki Sugawara, Masahiko Sugiura, Keita Kimura, Kuniyuki Takekawa Abstract Compound helicopter is one of the high-speed rotorcraft concepts. On the high-speed compound helicopter, rotor revolution is slower than the conventional helicopters, considering the effect of compressibility at the blade advancing side. In this case, a reverse・・・<<read more>>
